This Expeditions project engages two major communities: (1) organizations and individuals who have an interest in or responsibility for evaluating the degree of climate change and its potential impact in a variety of areas: weather, agriculture, economics, public health and safety, etc., and (2) researchers from computer science, high-performance computing, statistics, Earth and ecosystem science, and other sciences who can address the challenges implicit in the work we are undertaking. We are bringing these communities together by holding annual Workshops of the Expeditions project, as well as numerous other workshops and sessions devoted to understanding climate change through data at various conference and workshop venues.

Several team members are also engaged in project-related national and international activities. For example, Auroop Ganguly was invited as a reviewer for the IPCC's Fifth Assessment Report -- Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) prepared by the IPCC's Working Group II on Impacts, Adaptation and Vulnerability. He also served on a review panel of the United Nations Environmental Programme (UNEP) on Environmental Impacts of Climate Change and is a member of the American Meteorological Society (AMS) Committee of Artificial Intelligence Applications to Environmental Science.
